Posted by Troy Staten on December 17, 2023  Awesome machines, I believe these and the 5011 class locos where the most powerful 2 cylinder steam locomotives ever built. Thanks again for showing us these neat photos Posted by Jeff Sell on December 19, 2023  Thanks for sharing another gem from your collection. To respond to the previous comment - While this ATSF 2-10-4 was a power example of her class, the PRR 2-10-4 (J1 class) produced a whopping 95,000 lbs of tractive force with an additional 15,000 lbs available from her booster.
